Abstract
Description
Technical Field
[0001] This invention belongs to the field of luggage technology, and particularly relates to a quick-install wheel assembly and luggage. Background Technology
[0002] Currently, suitcases on the market can be categorized into three manufacturing processes: vacuum forming, injection molding, and thermoforming. Vacuum forming accounts for 80% of the market. (The basic principle of vacuum forming is: a mold is fabricated according to design requirements, placed on a processing platform, and a suitably sized plastic sheet is heated to soften it before being moved above the mold, forming a sealed cavity. A vacuum is then created within this cavity to expel air, causing the plastic sheet to adhere to the mold under negative pressure. Once the air is expelled, the plastic sheet is fully attached to the mold. After cooling, the mold is removed, and the product shape is set. Subsequent steps include trimming excess material.) The advantages of vacuum forming include lower development costs, lower mold costs, and ease of fabrication, making it very convenient for changing product shapes. Other accessories require screws for installation. With rising labor costs, relying on excessive manual labor for a single product is clearly not in line with current development needs. As artificial intelligence advances, automation in luggage production is becoming increasingly important, making quick and convenient assembly methods crucial for automated processes. Streamlining the assembly process significantly reduces labor costs and facilitates the use of automated production lines. Summary of the Invention

[0033] See Figures 1 to 3 In one embodiment, a quick-install wheel assembly includes a liner 1 and a wheel seat 2.
[0034] The inner liner 1 is used to install the wheel mounting position inside the outer housing 3. The inner liner 1 is provided with at least one first guide portion 101 and at least one first one-way locking portion 102 for extending out of the outer housing 3.
[0035] Wheels are mounted on the wheel base 2. The wheel base 2 has at least one second guide portion 201 corresponding to the first guide portion 101, and at least one second one-way locking portion 202 corresponding to the first locking portion. The locking positions of the first one-way locking portion 102 and the second one-way locking portion 202 correspond to the ends of the guide tracks of the first guide portion 101 and the second guide portion 201.
[0036] By setting an inner liner 1 and a wheel seat 2 equipped with wheels, a first guide portion 101 and a first one-way locking portion 102 for extending out of the outer casing 3 are provided on the inner liner 1, and a corresponding second guide portion 201 and a second one-way locking portion 202 are respectively provided on the wheel seat 2, with the locking positions of the two one-way locking portions set to correspond to the ends of the guide tracks of the two guide portions. This allows for easy installation by first placing the inner liner 1 inside the outer casing 3, extending the first guide portion 101 and the first one-way locking portion 102 out of the outer casing 3, and then sliding the wheel seat 2 into the first guide portion 101 through the second guide portion 201. When it slides to the end of the guide track, the first one-way locking portion 102 locks with the second one-way locking portion 202. This fixes the relative positions of the inner liner 1 and the wheel seat 2, and the outer shell 3 is clamped between the inner liner 1 and the wheel seat 2. The wheel installation can be completed in just two steps. The installation process is simple, the production process is simplified, the production cost is low, and it is easy to carry out subsequent intelligent and automated production, which solves the problem of complicated installation process of existing luggage wheels.
[0037] The specific structure of the quick-installation wheel assembly in this embodiment will be further described below:
[0038] In this embodiment, the inner liner 1 is provided with a fitting surface for fitting the inner cavity of the outer shell 3, so that the inner liner 1 can better fit the inner wall surface of the outer shell 3.
[0039] See Figure 4 and Figure 5 In this embodiment, the first guide portion 101 is a first T-shaped guide bar. The second guide portion 201 consists of two first L-shaped guide bars 2011 that are opposite to each other and spaced apart on the wheel seat 2, and the two first L-shaped guide bars 2011 cooperate with the wheel seat 2 to form a first inverted T-shaped guide groove 2012 corresponding to the first T-shaped guide bar.
[0040] Furthermore, the first T-shaped guide bar consists of several T-shaped guide blocks 1011 spaced apart. The purpose of setting the first T-shaped guide bar as several T-shaped guide blocks 1011 is to change the opening on the outer housing 3 from a large elongated hole to multiple small holes spaced apart, so that more of the outer housing 3 can be clamped between the inner liner 1 and the wheel seat 2, thereby increasing the stability of the connection.
[0041] In this embodiment, the first one-way locking part 102 is a one-way buckle. The second one-way locking part 202 is a groove provided on the wheel seat 2. The T-shaped guide strip and the T-shaped guide groove can limit the movement directions between the inner liner 1 and the wheel seat 2 other than the guide trajectory direction. The one-way buckle can be inserted into the groove to limit the movement between the inner liner 1 and the wheel seat 2 in the guide trajectory direction, thereby completing the locking.
[0042] Furthermore, the first one-way locking part 102 includes two second L-shaped guide strips 1022 and a locking block 1021 that are disposed opposite to and spaced apart on the inner liner 1. The two second L-shaped guide strips 1022 cooperate with the inner liner 1 to form a second inverted T-shaped guide groove, and the locking block 1021 is disposed in the second inverted T-shaped guide groove. The second locking part is a second T-shaped guide strip 2021 disposed on the wheel seat 2, and the second T-shaped guide strip 2021 is provided with a locking groove 2022 corresponding to the locking block 1021.
[0043] The slot 2022 has an inclined surface that matches the sliding direction of the second T-shaped guide bar 2021, which is used to limit the movement of the card block 1021 out of the slot 2022. Specifically, the inclined surface is inclined upward along the sliding direction. The purpose of this arrangement is to guide the movement of the card block 1021 into the slot 2022 through the second inverted T-shaped guide groove and the second T-shaped guide bar 2021.
[0044] In this embodiment, there are two first guide portions 101 and two guide portions 201. Of course, in other embodiments, the number of the two guide portions may be one or more, and no specific limitation is made here.
[0045] In this embodiment, both the inner liner 1 and the wheel seat 2 can be manufactured by vacuum forming and / or thermoforming processes, thereby reducing mold opening costs and production costs.
[0046] Example 2
[0047] This embodiment provides a bag, including a case shell 3 and the quick-install wheel assembly described in Embodiment 1 above. The bottom surface of the inner cavity of the case shell 3 has several through holes 301 corresponding to the first guide portion 101 and the first one-way locking portion 102. By providing an inner liner 1 and wheel seats 2, the inner liner 1 has the first guide portion 101 and the first one-way locking portion 102 extending out of the through holes 301 on the case shell 3. The wheel seats 2 have corresponding second guide portions 201 and second one-way locking portions 202, with the locking positions of the two one-way locking portions corresponding to the ends of the guide tracks of the two guide portions.
